Analog Devices SHARC EPROM and Host Boot Loader Tips and Tricks

About this manual

This document provides technical guidance for creating boot images for Analog Devices SHARC DSP processors using EPROM or host processors. It details the output of the elfloader tool and explains how to arrange data within the boot image for various processor models.

The guide covers specific DMA channel configurations and interrupt sources for different SHARC processor families, such as the ADSP-2106x and ADSP-21368. It also describes the structure of the boot kernel, including initialization sections and memory loading procedures required to transition from the boot loader to the user application.

Frequently asked questions

Which processors support booting through an external port?

ADSP-2106x, ADSP-2116x, ADSP-21367, ADSP-21368, ADSP-21369, and ADSP-2137x processors support booting through EPROM/flash connected to the external port.

Do ADSP-2126x processors support host booting?

No, host booting is not supported on ADSP-2126x and ADSP-21362 processors.

What is the default boot configuration for SHARC processors?

By default, SHARC processors are configured to load 256 words of 48-bit width by DMA.
